Brian-
If I were you I'd plan on going through the entire clutch. What you have has probably given 30+ years of service and it's just time to make it ready for another 30. Check out the manual section too to get a good idea as to what you'll be up against (if you don't have manuals on hand). I've done a few of these clutches and they all needed the bracket/pivot holes in the clutch arm welded up a little and resized along with a new pin (I have used 3/8" bolts for this pin). The working end of the same arm will need some attention as well from working the throwout bearing. Of course you can always go with new too. Another main concern with doing the clutch is having the pressure plates resurfaced. Be sure and inspect your drive shaft for wear. I'd replace the teaser spring with new for sure if it isn't broken already...prolly broken.
A couple of cents worth...good luck!
